In "Harrison Bergeron," why does George have to wear a mental handicap?

In
Vonnegut's classic short story "," the 211th, 212th, and 213th Amendments to the
Constitution, along with assistance from the Handicapper General and her agents, have created a
society where every citizen in the United States is completely equal in all facets of life.
Above average citizens with more athleticism are forced to wear heavy, cumbersome handicaps
while beautiful individuals are required to wear ugly masks. Citizens who have above average
intelligence are also required to wear a mental handicap radio in their ears, which makes
extremely loud noises every twenty seconds in order to interrupt their thoughts.
Harrison Bergeron's father, George, was born with above average intelligence,
which is why he is required to wear the loud mental handicap radio in his ear. In
the third paragraph of the short story, Vonnegut writes,

"And George, while his intelligence was way above normal, had a little mental
handicap radio in his ear. He was required by law to wear it at all times. It was tuned to a
government transmitter. Every twenty seconds or so, the transmitter would send out some sharp
noise to keep people like George from taking unfair advantage of their brains (1).
